4-METHYL-1-NAPHTHYLMAGNESIUM BROMIDE, 0.25 M SOLUTION IN TETRAHYDROFURAN - Introduction
bromide is an organic compound with the chemical formula C11H9BrMg. It is a strong alkaline, highly reactive organometallic compound. The properties and uses of the bromide are as follows:
Nature:
-Appearance: Liquid bromide colorless to yellow
-Solubility: It has good solubility in non-polar organic solvents, such as ethers and hydrocarbon solvents
-Reactivity: It can undergo addition, substitution and ortho-electrophilic substitution reactions with a variety of organic compounds
Use:
-bromide is an important reagent in organic synthesis and is often used to construct carbon-carbon bonds and carbon-heteroatom bonds.
-It can be used as an intermediate for the synthesis of natural products, pharmaceuticals and pesticides
-bromide can also be used in the preparation of Flynn A, which is commonly used in industries such as surfactants, rubber accelerators and preservatives
Preparation Method:
Calcium bromide is generally prepared by the Grove reaction, which is formed by reacting 1-bromomethylnaphthalene with magnesium. During the reaction, the temperature and reaction conditions need to be controlled to ensure the yield and purity of the product.
Safety Information:
-bromide need to stay away from fire and oxygen, avoid contact with skin and eyes
-During use and storage, care should be taken to prevent irradiation and avoid contact with acidic substances, oxidants and water
-Wear protective glasses, gloves and protective clothing when operating
-Please read the relevant safety instructions carefully before use and follow the correct operation instructions and disposal measures
